Thomas Kolding ran away from his Mountain Lakes home on the day before Halloween after having an argument with parents over his grades at school.

The family hasn't heard from him since, but surveillance cameras last captured him Nov. 3 at the Walter Rand Transportation Center in Camden. Police said he also was seen that afternoon in Philadelphia.

Police in Miami Township, Ohio, on Friday said they received reports that the youngster may have been spotted there, more than 500 miles from Philly.
